September 2-3, 2010 (Thursday, Friday)
DUE:
Turn in LAB REPORT #2 for What's the Matter?
One lab report turned in per group.
Lab report is worth 25 points.
Everyone in the group gets the same grade.
Quiz #6 over class notes and experiments completed (5')
THINKWELL VIDEO: Properties of Matter (7')
Class NOTES for video Properties of Matter (print off ahead of time if you want)
Teacher presentation: Power Point Presentation over Elements, Compounds and Mixtures (30') - Do NOT print this off....see next bullet!
Class NOTES for Matter- print these off ahead of time if you want the slide show on paper with places for taking notes
IN CLASS - LAB EXERCISE: How to read a thermometer (30')
Calibration: meaning of the smallest marking on a measuring instrument
What is the calibration of your thermometer?
To what decimal place will you record your temperature values?
Calibrate - using a control to allow you to determine an accurate measurement
On your thermometer, what is the temperature of the ambient air?
On your thermometer, at what temperature does ice in water read?
On your thermometer, at what temperature does tap water boil?
HOMEWORK:
Read Chapter 3.1 - Properties of Matter
Complete the Section 3.1 Assessment Pg. 60 #1-5
Read Chapter 3.2 - Changes in Matter
Complete the Section 3.2 Assessment Pg. 65 #10-14
STUDY your notes from class and from Chapter 3.1 and 3.2 - you will have a quiz over this next time
September 6, 2010 (Monday) - Labor Day!
September 7-8, 2010 (Tuesday, Wednesday)
Turn in Pgs. 60 #1-5 and Pg. 65 #10-14
Quiz #7 over Chapter 3.1 and 3.2 (10')
Hand back two lab reports (#1 and #2) - 20'
Review Mrs. Weir's "sample" lab report. Compare that to your own. What's similar? What do you need to improve on?
How to make a data table.
EXPERIMENT - LAB #3: Does adding salt to distilled water raise its boiling point? (60')
Calibrate your thermometer using 100 mL of distilled water to its boiling point
Measure out 15.00 g of table salt (NaCl) using the triple beam balance
Add the 15.00 g of table salt to 100 mL of distilled water - boil and measure temperature
Record the accurate temperature reading, adjusting to the calibration of your thermometer used.
By how many oC did adding salt to water raise the boiling point of water?
Repeat the process above but now using 15.00 g of table sugar (sucrose).
LAB #3 REPORT:
Purpose - Use one or two complete sentences. Make it concise (no wordiness) - just get the job done.
Materials and Tools - List them using bullets.
Procedure - Using numbered steps, specifically describe, step-by-step, what you did.
Write in "third person"and use complete sentences.
NEVER use "I" or "we" or "they" in a procedure.
You are writing these steps like you might see in a recipe.
Data table - Create and enter data (be sure to include units)
Calculations - Show all work and clearly identify your final answer
Summary - Use a couple of sentences to explain each question below.
Why is calibration of the thermometers necessary?
How did you determine the calibration of your thermometer?
Why should you use the same thermometer for multiple temperature measurements in the same lab?
Why would the "adjustment" (above or below the "correct" theoretical temperature) NOT be the same for the ice water and boiling water?
WHY would the boiling point of salt water be higher than the boiling point of tap water?
WHY would there be a difference between adding SALT vs. SUGAR to water in terms of raising the boiling point?
Resources - See questions above.
HOMEWORK:
Complete LAB REPORT #3 - see details above
Read Chapter 3.3 - Mixtures of Matter
Complete the Section 3.3 Assessment Pg. 69 #15-19
Read Chapter 3.4 - Elements & Compounds
Complete the Section 3.4 Assessment Pg. 77 #25-30
STUDY your notes from class and from Chapter 3.3 and 3.4 - you will have a quiz over this next time
BE SURE TO BRING YOUR TEXTBOOK TO CLASS NEXT TIME
